F12 error code on a gas Frigidaire range? Here’s how to troubleshoot it

Are you seeing an F12 error on your gas Frigidaire range? This error usually means there’s an internal software failure within the Electronic Oven Control (EOC) module. The EOC interprets user input and regulates the range’s oven functions. But an internal software issue can trigger the F12 display to let you know that something has gone wrong with the EOC’s programming.

Since the EOC is like the “brain” of the oven, any software glitches can mess up the range’s cooking and baking performance. Thankfully, you should be able to troubleshoot this issue yourself without calling a repair technician.

If you find out that you need any replacement parts for your Frigidaire gas range, you can enter your model number at AppliancePartsPros.com to order them. Most orders arrive in just two business days, and we have thousands of free guides to show you how to install your new parts.

Keep safety first

Your safety should always be the top priority when performing any appliance repair:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Shut off the gas supply to prevent any gas leaks while you work.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can clearly see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

Troubleshooting steps

Step 1 – Reset power

To diagnose and resolve issues with the EOC, you should start by resetting the power. Sometimes a simple reboot can fix the problem.

1. Shut off power at the circuit breaker or unplug the range and turn off the gas supply.
2. Wait for at least 30 seconds to make sure the board is reset.
3. Restore the power and gas supply to the range and see if the error code shows up again. If it does, you need to replace the EOC Module. You’ll also want to get a new overlay since the old one may not adhere to the new EOC Module.

Step 2 – Replace the EOC module

To replace the EOC module, turn the range off and turn off the gas supply, then follow the instructions in the service manual to carefully disconnect all power and data lines from the faulty EOC. Then you can pop in a fresh EOC and reconnect all the terminals.
